WALL - mini-game

night_hawk · Post by **night_hawk** » Tue May 06, 2008 8:25 am

It's not much... more of a tech-demo of sorts. It's got a wall and a brick launcher. Get it? Launcher? Wall? Grr... you have a wall to destroy.

It uses Ageia PhysX (You'll need the small drivers) and BlindSide's XEffects for Shadows (They can be disabled if they don't happen to work with the custom settings).

Get both the drivers and the game from this link.

Source code is also available at the link above.

I would also love some technical feedback on this one. (Framerate, framerate changes over time, crashes, etc)

Have fun!

P.S.: I might give the source if people are interested.

Cute.

It crashes even with all options disabled

I think it has to do with the PhysX, I have the latest drivers though so I'm not sure whats happening.

Cheers, could you post some screenshots as I am interested how the shadow mapping looks.

EDIT:

Oh yeah:

Windows XP 32-bit
AMD Turon ML-30
Radeon 200M

AGEIA PhysX drivers installed from v2.3.1 to v2.7.4

EDIT2:

Nevermind, it works after I installed v2.8.0, but really, PhysX should fix their software, it shouldn't just crash without any notification if I have the wrong version installed.

Few gripes:
I can't see any shadows with them enabled, if you want I can take a look at the source and tell you whats going wrong.
Also, under low FPS (8-10), the blocks travel so fast that they just go through the wall, you might wanna enable some kind of infinite recursion thing like Bullet, or trace a ray or something.

Cheers

I ran it, it's pretty cool. But as mostly what BlindSide said, I don't see any normal mapping, no shadows. The lighting does work. And also, why does FPS drop to 25 with the hard wall, but is at 90 with a soft wall?

No normal mapping or shadows? That's weird. Yeah, I'll up the source code and feel free to check, but those are the 2 things that I expected to work for everyone

(And they did work for quite a few people... anyway...)

@Halifax: the framerate drop from "easy" to "hard" is because of the joints. There are... let me see... about 200 joints I think. Those are slowing down the whole game a lot. Destroy them and the framerate goes up

And yes... I should have probably used CCD

Thanks for the info!

Ah yes, I was wondering if that was the reason because I could see that some parts of the wall were sticking together even after I broke it from the main wall.

Anyways, great techdemo so far. It would be cool if you could make a nice little sandbox type physics thing, but now I know I am asking for to much.

Very nice demo! It has a lot of different examples (integrating physx, shadows, shooting from camera, lighting, normal mapping, GUI, etc!)

I love when you get really close to the brick you can see it shimmer

Any sources

Sources coming up in a few minutes. Let me clean them up a bit.

EDIT: Sources up.
